Title: Improvements in or relating to pattern copying machines
IPC: B27M3/20
Filed: 1930-05-28
Abstract: 355,798. Pattern grading machines. BRITISH UNITED SHOE MACHINERY CO., Ltd., Union Works, Belgrave Road, Leicester.-(United Shoe Machinery Corporation : 140, Federal Street, Boston, U.S.A.) May 28, 1930, No. 16409. [Class 97 (iii).] A pattern grading machine comprises four primary instrumentalities, viz., a model holder, a work holder, a model follower and a tool, suitably interconnected for relative motion to reproduce pantographically upon a work piece in the work holder a model in the model holder, and mechanism for imparting to one instrumentality a non-pantographic reproductional movement in a certain direction, adapted to be operated by relative movement of two of the instrumentalities while both are in ordinary pantographic grading motion. As shown in the Figure, there are five principal mechanisms. The first, which effects north and south movement between the tool 30 and the model follower 22 due to east and west movement between the primary instrumentalities, comprises the arc 78 which shifts the fulcrum 47 of the width grading lever 36 as operated by the bars 94, 100 and the carriage, that is by the length grading movement. Either of the bars 94, 100 may be pivoted to the bar 82 by movement of the handle 92 in opposite directions. In the central position of the handle 92 the arm 82 may be clamped to the bracket 50. The second has the same function as the first but operates when there is no length grading, and comprises the arc 78 driven by the length grading lever 32 through the. link 130, the lever 124, and the bars 94 and 100 as before. The third alters the width grading factor by effecting north and south movement between the tool and model follower due to north and south movement between the primary instrumentalities, and comprises the arc 78 as driven by the width grading lever 36 through the arm 160. The fourth mechanism alters the length grading factor by effecting east and west relative movement between the model follower 22 and the cutter 30 due to east and west movement between the primary instrumentalities, and comprises the pivoted arc 152, and the link 154 as driven by the length grading lever 32 through the link 156. The fifth mechanism effects east and west movement between the follower 22 and the cutter 30 due to north and south movement between the primary instrumentalities, and comprises the pivoted arc 144 and the link 146 as driven by the width grading lever 36 through the links 136, 138 and the crank arm 140. Specifications 335,200, [Class 79 (iii), Motor vehicles, Arrangement &c. of parts of], and 350,940 are referred to.

Title: Process of and apparatus for welding
IPC: B23K11/00
Filed: 1927-06-23
Abstract: 297,493. Beatty, W. E., (Bell Telephone Laboratories, Inc.). June 23, 1927. Controlling consuming devices.-In a process of welding copper wires, rods, &c. the abutting surfaces of the parts are electrically heated to a temperature higher than the welding temperature, are then cooled to welding temperature and are then percussively engaged with each other. The welding circuit contains either a number of nickel wires or a variable inductance to vary the heating effect. The copper rods &c. 9, 10 are secured with wedge-shaped ends abutting at right angles in a fixed and a movable pair of jaws 7, 8, respectively. The jaws are connected to the terminals of the secondary 34 of a transformer. In the conductor between the jaw 8 and the transformer are located in parallel a number of nickel wires 36 which, when cold, allow a large flow of current, but which, on account of their high temperature coefficient of resistance, limit the current as the temperature increases. The welding switch 37 is closed against the action of a spring 38 by the relay 36 of a control circuit provided with switches 39, 41. The inner sides of the jaws, 7, 8 are made parallel so as to form together the work a single turn of a coil, the effect of which, when the current is switched on, is to cause the jaws to separate magnetically and serve as a magnetic blow-out. On withdrawing a pin 48 the switch 39 is closed so as to complete the welding circuit, and a weight 46 is released. The ends of the rods are immediately fused and the molten parts are removed from the joint by the magnetic blow-out. An account of the inertia of the weight 12, a gap remains between the ends of the work. The current is automatically reduced by the nickel wires so that the work begins to cool and at a predetermined period of movement of the jaw 8 a screw stop 43 thereon opens the switch 41 and thus cuts out the current to allow the parts to cool to welding temperature. In a modification, the nickel wires are replaced by a variable inductance 64, Fig. 4, consisting of a yoke 65, a coil 67 of a few heavy turns wound on a non-magnetic tube and a movable core 68 so that the initial current is large so as to heat the parts and is reduced so as to allow the parts to cool to welding temperature as the core, which has considerable inertia, is drawn forward against the action of a spring 69'. Specification 271,431 is referred to. The control circuit is completed by a push button switch 39.

Title: Method of and means for converting sea water to fresh water by evaporation
Inventor: SMITH EWEN HENRY
IPC: C02F1/16
Filed: 1950-07-05
Abstract: <PICT:0716603/III/1> Sea water is distilled by passing exhaust steam from auxiliary engines through the coils of the evaporator which contains the sea-water, the vapour space of the evaporator being connected, preferably via a heat exchanger for condensing the water vapour generated in the evaporator, to a condenser which is evacuated by means of exhaust steam which flows in parallel with that supplied to the coils of the evaporator.  The condensate from the coils of the evaporator and that from the vacuum condenser are led to a boiler feed water tank.  The apparatus shown comprises two groups of auxiliary engines 1 and 11, an evaporator 4 heat exchanger 14, and vacuum condenser 10; the condenser 10 being connected via pipe 19 and valve 20 to heat exchanger 14, which is itself connected to the vapour space of evaporator 4 via pipe 16.  Heat exchanger 14 and vacuum condenser 10 are cooled by circulating sea water through pipes 15 and 13 respectively.  Auxiliary engines 1 feed exhaust steam through pipes 2 and 5 to the coils 3 of evaporator 4.  Exhaust steam from engines 1 is also supplied (as a source of heat) to boilers (not shown) via pipe 7, and via pipes 8 and 9 to vacuum condenser 10; pipe 8 being fitted with a valve 22 in order to maintain a steady back pressure in the exhaust of engines 1. The exhaust steam from engines 11 is supplied via pipe 9 to vacuum condenser 10, a steam jet air ejector serving to create a vacuum in the condenser.  The condensates from condenser 10 and coils 3 flow, via pipes 23 and 24 respectively, to boiler feed water tank 21.  The fresh water condensed in heat exchanger 14 is drained off through pipe 17 to a storage tank (not shown) at atmospheric pressure.

Title: Improvements in or relating to Means for Preventing the Overheating of Steam Superheater Tubes.
Inventor: ARMSTRONG JOHN EDWARD
IPC: F22G3/00
Filed: 1918-04-13
Abstract: 129,536. Armstrong, J. E. April 13, 1918. Overheating of superheating-tubes, preventing. - Relates to an automatic valve-device for admitting an auxiliary supply of steam to a superheater when the regulator is closed, the auxiliary supply being cut off when the regulator is opened and the steam remaining in the superheater exhausting through the blower to the atmosphere. The device is provided with means for closing the valve controlling the auxiliary steam supply, and at the same time maintaining the valve connecting the superheater to the atmosphere in its open position. When the regulator is closed, boiler steam admitted through a connexion d lifts the auxiliary steam supply valve c and passes through a connexion e to the saturated-steam header. The valve lifts a piston h, which in turn lifts the valve b between the connexion f leading from the saturated-steam header and the steam outlet g leading to the blower. Boiler steam may be admitted through a connexion j to a space between the top of the piston h and a piston b<1> on the valve b so as to force the valve c on its seat, at the same time keeping the valve b in its open position. The steam supply through the connexion j may be controlled by a three-way cock allowing steam to pass direct to the blower.

Abstract: 1346854 Digital data readout HONEYWELL INFORMATION SYSTEMS Inc 25 May 1971 [19 June 1970] 16998/71 Heading G4C A digital data reading apparatus decodes an input data stream, e.g. in a self clocking code such as double frequency or phase encoding, to provide separate data and clock signal outputs. The apparatus receives a stream of data and sync. pulses from a magnetic disc 10 and uniform width pulses are produced by monostable 102 and emitter follower 103 to give waveform (b), Fig. 2. A ramp signal is generated for each of the pulses of the input data stream in unit 106 (waveform (e), Fig. 2) and the ramp signals pass to a variable threshold switching circuit 140. At the same time waveform (b) passes through a filter 180 which produces bell-shaped pulses (waveform (c)) which trigger an oscillator 280 (a resonant tank circuit) to produce a sinusoidal waveform (a). A crossover detector 290 generates clock output pulses (waveform (d)) from predetermined sets of crossover points of the waveform (a). By adjusting the threshold of the switching circuit 140 the pulses of the data stream (waveform (f)) are arranged to be in 180 degrees out of phase relationship with the clock waveform. A phase sampler 2, 10 has been comparing the time occurrence of the pulses of waveform (c) relative to the zero crossover points of waveform (a) for deriving an error voltage proportional to the phase difference therebetween. Using integrators 240, 270 a correction voltage is applied to the tank circuit 280 which adjusts its frequency at a critically damped rate to decrease the discrepancy in phase. The waveforms (f) and (d) pass to data recovery logic 300 (Figs. 3, not shown) where control signals are generated which define the intervals during which the data pulses of the input data stream are to be sampled for content (i.e. decoded into binary's 1's and 0's). In the absence of a predetermined number of pulses in the data stream the amplitude of the reference signal from the tank circuit reduces so as to inhibit production of the clock pulses.
